Trip to Argolis (Corinth,The Great Theatre of Epidaurus,Nafplio)

The Ancient Theatre of Epidaurus is a theatre in the Greek city of Epidaurus, located on the southeast end of the sanctuary dedicated to the ancient Greek God of medicine, Asclepius. It is built on the west side of Cynortion Mountain, near modern Lygourio, and belongs to the Epidaurus Municipality. It is considered to be the most perfect ancient Greek theatre with regard to acoustics and aesthetics.
According to Pausanias, the ancient theatre was constructed at the end of the 4th century BC[2] by the architect Polykleitos the Younger.[3] Pausanias praises the theatre for its symmetry and beauty.[4] At a maximum capacity of 13,000 to 14,000 spectators, the theatre hosted music, singing and dramatic games that were included in the worship of Asclepius. It was also used as a means to heal patients, since there was a belief that the observation of dramatic shows had positive effects on mental and physical health.

The Corinth Canal connects the Gulf of Corinth in the Ionian Sea with the Saronic Gulf in the Aegean Sea. It cuts through the narrow Isthmus of Corinth and separates the Peloponnese from the Greek mainland, arguably making the peninsula an island. The canal was dug through the isthmus at sea level and has no locks. It is 6.4 kilometres (4 mi) in length and only 21.4 metres (70 ft) wide at its base, making it impassible for many modern ships.
The canal was initially proposed in classical times and a failed effort was made to build it in the 1st century AD.[2] Construction recommenced in 1881 and was completed in 1893.

Palamidi is a fortress to the east of the Acronauplia in the town of Nafplio in the Peloponnese region of southern Greece. Nestled on the crest of a 216-metre high hill, the fortress was built by the Venetians during their second occupation of the area (1686–1715).

Nafplio, Nauplio or Nauplion in Italian and other Western European languages) is a seaport town in the Peloponnese in Greece that has expanded up the hillsides near the north end of the Argolic Gulf. The town was an important seaport held under a succession of royal houses in the Middle Ages as part of the lordship of Argos and Nauplia, held initially by the de la Roche following the Fourth Crusade before coming under the Republic of Venice and, lastly, the Ottoman Empire. The town was the capital of the First Hellenic Republic and of the Kingdom of Greece, from the start of the Greek Revolution in 1821 until 1834. Nafplio is now the capital of the regional unit of Argolis.
